Cause: PU board powerfail comes when power unit power supply failure. This means there is an hardware issue in powerboard.
A5EB warning in ABB ACS880 drive indicates PU board powerfail. This means there's a problem with the power unit's internal power supply.
Solution:
- Check input supply.
- Power recycle drive.
- Check drive hardware using multimeter.
